Application filed' December This invention relates'to a new" and imi`proved cutter or mill and means andmethod of making cuts lin theoppositely disposed faces of a toolsuch as pliers, 4wrenches or theflike.

lt is'the object of this inventionyamong other things, to produce acutter or mill that will not only make-peripheralecutsbut also .sidecuts,` asmay be desi-red, andtomakefat one; and the san1e^time--ithesecuts in the op! s posite'faces of the jaws -of a pair of pliers,

wrench orA similar tools.

Referring to the "drawings, in 4wh! chl like" numerals of referencedesigna-te like parts in the severalliigures;

Figurel isja side elevationoffone formA of my improvedcutter'or'mill andthe arbor upon which itis' mounted and a pair of pliers positionedv foroperation thereonjby the cutter; v

Figure 3is" a vie-w",similar-toI that shown in F igure'v2 with a cutteror mill of different form and Figure t "is a fragmentary View oftheface, with the cross cutsftherfein, of one of the jaws of a pair ofpliers and a. portion of another ja'w 'connectedt-herewith'.I4 I 1 Sofar as applicant ,'s advised, no one has heretofore produced a cutter ormill with teeth upon the side faces thereof that are relieved from thecutting edges so that they actually take a cut instead of being draggedor drawn over the surface to be operated upon and remove the material byabrasion rather than cutting. Applicant has y designed a cutter or millhaving these desired characteristics and Vhas made possible the makingof cuts in the opposing faces of the jaws of a pair of pliers, wrench orthe like at one and the same time. v

In the drawings, oneform of my new and improved cutter or mill,designated 10, is

.mounted upon an arbor 11, as is usual, and has a plurality of teeth 12around the periphery thereof, from which lead grooves 13 in the sides ofthe cutter which may be radial, or if desired, angular or tangential, asshown in Figure 1.

In this form of cutter the sides thereof, adjacent to the periphery, areprovided with 3,1955: serial No. 73,028;

rounded portions 14, and leading. therefroml` allgl anglev` thereto arethe sid-e' faces rlhe grooves 13- are staggered invv relation' toeach-,othertupon opposite Isidesof the cutter `(Figure i2), thatfis,thegroove' `V13 upon one-sideoffthe cutter is' midway 4Abetvife'en" twosimilar'grooves-onthe oposite-sidfe-of 7 the cutter, so `that "in:operationk the .fteetl upon oppositesi'des oftheA cutvtrer'cut"alte-rfna'tely, relievingthe pressure upontlie 'tool aswelllasthe article being'op'eratedluponif `Theouterfalces of the portior'is'lareV pro?vided'with teeth'concentric with the'ffaxisf'ofv the cutter and'faces15.-15"adj a'centfl thereto with similar teeth. n These teethl are shownas being'of' different sizesythat 'is,-those" on"thefacesf'beiiigsmaller than' thoseon' 'the portions'y 14:.Obviously,they may be ofthe same siz'eor their' relative sizes changed"asl may be desired'.

Inthexform'of* cutter shown l'the side faces of the Iteethy 12 'havenoteeth' therein` ysimi'lar to those in thefportionsllt andsiderfaoes"15,1` although they? may beso provided if'de-l sir'edk c.

Inthe' form 'shown in Figure 3, the'cutf kter ;16-has substantiallyparallely side faces,

the teeth l15T-therein being r concentric*with` the ,aXis'of`-tlnecutter and staggered' infrelation to each other upon opposite sidesthereof.

My improved cutter is especially effective is integral with the jaw 18.vThese jaws are l assembled before being presented to the cutter upon asupport 21 of any preferred form or shape and are movedtoward each othermanually, each of thev opposing disposed gripping faces of the jawssynchrolnously engaging opposite sides of the' cutter. This has notheretofore been possible, it being necessary tocut the face of each jawseparately yand thereafter assemble'such jaws. In Figure 2, each jaw islshown with a recessed portion 22 in the face of which, cuts are made bythe teeth on the portiony 14, and leading therefrom, toward thev stud 2Ois a substantially straight` face 23, out by the teeth l2 so as to leavea straight edge thereon, which, .when the jaws are closed, Vare utilizedto cut wire or the like. By this cutter, the straight portion of thejaws adjacent tothe recessesi22 kare provided vwith smaller cuts 24.

With the cutter and pliers held in the po-V if vBy the use of thiscutter land the means herein disclosed, for the purpose described, Workof very-high degree of perfection is produced in the minimum time and atthe lowest possible cost, and without the. aidof tools other than thecutter itself.

`In .Figure4, I have illustrated one of rthe jaws having two cuts in theface thereof lcrossed in relation to eachother forming a cross checkjaw. This form of cutting is obtained by use of the saine tools as aboverdescr1bed,byr simply placing the tool first. above the center of thecutter so that it will occupy the position substantially as shown by thedotted lines 25 in Figure. l, and then in the position substantially asshown by the broken lines 26', that is, the

jaws are pressed against the sides of the cutter at points above andbelow the horizontal center thereof. The cuts shown are circular butthey may be made substantially straight, although not actually straight,by merelyenlarging the size of the cutter.

The form of cutter shown in Figure 5 is designedfor making the cuts inthe jaws kwhen the same are to be parallel with each that may be madewithin my invention,

aside from those herein suggested, and I would therefore have itunderstood that I do not limit myself to the exact construe-v tionherein shown and described, but claim all that falls fairly withinthespirit and scope of the appended claims.

Having described my invention, what l' claim as new and desire to secureby Letters'Patent, is Y l. A. circular cutter having aplurality'ofseries of cutting teeth on each side face thereof, which teeth areconcentric and spaced by grooves extending from the cen ter of thecutter toward the vperiphery thereof, the grooves on one side face ofthe v cutter being staggered relativek to the grooves on the oppositeside face of the cutter whereby to cause alternative cutting andconsequent relief in pressure upon the vcutter as well as upon the work.

2. A circular cutter having a concentric rounded portion on each sideface thereof spaced from' the center of the cutter, the side faces ofthe cutter between the rounded portionsand the center of the cutterbeing divergent relative to the center, and concentric teeth on theYrounded portions 'and on the divergent portions.

In testimony whereof, I have hereunto afIiXed my signature.
